Hello, the game runs pretty smoothly on my computer (linux gentoo x64) except for a strange issue - it takes a long time to start. About 3 to 5 minutes, which made me think it wouldn't boot up the first time, but after some patient waiting it worked. Then whenever I finish a level (ie. the game saves) I have to wait for about 30 seconds while the game is unresponsive. My initial hunch is that it's spinning a lot on disk IO. I don't have an SSD, but this is pretty excessive.
Apart from that I'm really enjoying the game, and I'm sure it will be even better with time. One suggestion: I'd like to have the output of a gate light up if it's gonna output high, this way I can know its result without connecting a dummy gate / output to it.
